Flash memory is an electronic non-volatile computer storage medium that can be electrically erased and reprogrammed.
Introduced by Toshiba in 1984, flash memory was developed from EEPROM (electrically erasable programmable read-only memory). There are two main types of flash memory, which are named after the NAND and NOR logic gates. The individual flash memory cells exhibit internal characteristics similar to those of the corresponding gates.
Whereas EPROMs had to be completely erased before being rewritten, NAND type flash memory may be written and read in blocks (or pages) which are generally much smaller than the entire device. NOR type flash allows a single machine word (byte) to be written—
The NAND type is primarily used in memory cards, USB flash drives, solid-state drives (those produced in 2009 or later), and similar products, for general storage and transfer of data. NAND or NOR flash memory is also often used to store configuration data in numerous digital products, a task previously made possible by EEPROM or battery-powered static RAM. One key disadvantage of flash memory is that it can endure relatively small number of write cycles in a specific block.
NAND may stand for:

This video explores an old topic of ours and discusses NAND Flash for SSDs. We talk SLC, MLC, and TLC NAND, discuss which is "best" (and if there is a "best"), and talk about how NAND/SSDs work.

1. No need extra Computer and Software, it can change 32 & 64 Bit Nand Flash Data, such as SN (Serial Number), Model, Region,Color and others for iPhone 4s/5/5c/5s/6/6+, iPad 2/3/4,Mini/2/3/4, iPad Air/2 32 5S/6/6+; 2 Can expand the capacity by change Nand Flash; 3. Can fix some error report when restore with iTunes

This video is just for reference. It show you the whole procedure how to expand iPhone 6 memory from 16GB to 128GB. With the similar way, you can do iPhone 6 plus. And remove 64 bit NAND iPad iCloud (mini2/3/4,air/air 2). If you want to unlock iPad mini 1,iPad 2/3/4, you need 32 bit IC Programmer.
